That's because that's literally their role. Think about all of the meaningless laws that exist: We all have to drive our cars certain speeds so little Jimmy stays safe. Instead of just watching the road and teaching your kid not to be a mongrel, the blue gang of Thieves enforces hilarious moronic laws like "don't drive that fast". All they do is watch people that commit these "crimes" and use the opportunity to secure more debt for their overlords. Think of it as a forceful extraction like Masonic dues, or interest rates. Their whole role is to secure debt collection.
